This course will cover programming language-based techniques which apply to software development, software verification, models of computation, and logical foundations of mathematics. Related sub-topics include programming language design, compiler implementation, program analysis, software security, and higher-order logic. Course topics will be approached from the perspective of type theory. Coursework is intended to be a 50/50 split between exercising mathematical concepts and implementing algorithms.

Course Piazza: CS 225: Programming Languages
Course announcements and discussion will take place on Piazza exclusively.
The textbook we will use for this course is Pierce's Types and Programming Languages. It is highly recommended you obtain a personal copy to use throughout the course. Homework problems will be drawn directly from this textbook, and the exams will be open textbook in addition to only one page of other notes.
Programming Language: Many of the assignments will have a programming component. We will use the OCaml programming language for these assignments. For the first assignment you will be required to successfully set up and configure OCaml on either your personal machine or a computer lab machine. We will use OCaml version 4.06.0 for the entirety of the course.
Instructions for setting up OCaml
Git and Version Control:
LaTeX and Formal Writing: Many of the assignments will have a written mathematics component. If you want to write your solutions on a computer, I recommend using the LaTeX typesetting system. However, using LaTeX is not required for assignments. Using LaTeX will be required for the final project.
Grades: Your grade for the course will be calculated as follows: 60% Assignments (6 assignments at 10% each assignment), 20% Midterm Exam, and 20% Final Project. The last assignment is a final project checkpoint. In total, the final project (checkpoint assignment + final submission) is 30% of your final grade.
Attendance: Attendance is not mandatory but will be rewarded. Attendance will be taken every class. Students who miss no more three classes will receive an automatic 5% extra credit to their final grade.
Exams: There will be one midterm on March 08, and one final exam on May 03. Each exam will be open textbook, meaning you may reference the Types and Programming Languages text during exams. You will also be allowed one physical page (8 1/2" x 11") of notes for each exam. There is no final exam, and this course will conclude before the University's exam period.
Late Work: Each assignment will typically be released on a Sunday night, and due a week from the following Monday at 11:59pm. I will automatically grant a deadline extension up to that Wednesday at 11:59pm. You do not need to email me or any TAs to receive the extension---it is automatic. There is no penalty for submitting work before Wednesday at 11:59pm. Work will not be accepted after Wednesday at 11:59pm except in the case of personal emergencies.
Collaboration: Collaboration on the high-level ideas and approach on assignments is encouraged. Copying someone else's work is not allowed. Any collaboration, even at a high level, must be declared when you submit your assignment. Every assignment must include a collaboration statement. E.g., "I discussed high-level strategies for solving problem 2 and 5 with Alex." Students caught copying work are eligible for immediate failure of the course and disciplinary action by the University. All academic integrity misconduct will be treated according to UVM's Code of Academic Integrity.
Invited Talks: I will give +1% extra credit to your final grade (~10 assignment points) for each faculty candidate talk you attend. You must write 10-20 sentences about what the candidate talked about, and what you found interesting about the presentation. Specifically, you must include (1) the candidate's main research result, and (2) the candidate's proposal for future research. I expect each candidate will have slides indicating these points directly. If they don't, say in your writeup that the speaker wasn't specific regarding these points. You must email me your writeup within 24 hours of the talk to receive credit. See the Piazza announcement for dates, times, locations, and talk titles.

Small Group Assignments
For homework 4 and 5 only you will be allowed to work in groups of size 1–2 (independently or in pairs). You may submit a single solution to the assignment, as well as a writeup of how the group arrived at the final solution. There will be more detailed instructions about how to submit groupwork in the assignment writeup.
Final Group Project
We will have a final project instead of a final exam. You will be allowed to work in groups of size 1–4 for the final project, however I will expect a larger amount of work to be completed as group size increases. See the final project page for more details.
